Hygric and Thermal Simulation

Hygrothermal examination of a window connection

The following case shows how HTflux can help examining details that are problematic from a hygrothermal perspective.
In the present example incorrect construction is causing significant mold growth. The thermal and hygrothermal simulations carried out with HTflux reveal a problematic configuration of the interior insulation and vapour barrier. The thermal simulation already shows that the vapor barrier is installed at a location having a too low temperature. A more precise inspection using our unique Glaser-2d simulation clearly demonstrates the condensation at the surface of the vapour barrier.
